错误信息:
Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed;
nested exception is org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://PROVIDER/add": PROVIDER;
nested exception is java.net.UnknownHostException: PROVIDER] with root cause
java.net.UnknownHostException: PROVIDER
看到有人说修改localhost 为本机IP 尝试也没有效果
上面是引起错误的代码。
这是正确的代码
加上@LoadBalanced
RestTemplate java.net.UnknownHostException
